Clinical course of mild traumatic brain injury in polytrauma patients admitted to intensive care.

Among 244 patients (82% male, mean age 41.3 years), 82.8% had traumatic intracranial lesions.

Independent predictors of neurosurgical intervention included epidural hematoma, midline shift > 5 mm, and assault-related trauma.

Mortality was associated with age and hemorrhagic shock.

Functional outcomes were favorable in most patients, but 24% had disability at discharge.
